Unordered (bulleted) list

The most commonly used list is the unordered list. An unordered list can be used whenever the order of items you want to list is unimportant. HTML offers three different default characters to use with an unordered list: a bullet (), a circle (), and a square (). The following shows examples of an unordered list:

Unordered list  type bullet (default)

Unordered list  type circle

Unordered list  type square

The other popular kind of list is the ordered list. This type of list can be used when the order of items to list is important. It could be that you want to list steps to how to cook a recipe; for this kind of list you could use an ordered list because each step can be emphasized numerically. An ordered list can be created with different styles: Arabic numbers, lowercase or uppercase letters, or lowercase or uppercase Roman numerals. The following shows examples for each of these styles:

Ordered list style: lowercase letters
